Accountant Calculator is the perfect calculator for general everyday use. Use it for adding columns of numbers, invoicing, point-of-sale receipt generation, income taxes, VAT and percentages, and much more.

Q1. What is the difference between this App and Interlocken's 'Adding Machine: 10 Key Calc' in the App. Store?
A1. Both calculators are single-column adding devices. Both have iPad versions with full-size (1:1) keyboards. 'Accountant Calculator' supports the free chaining of +, -, x, /, %, √, 1/x and is easier to use if you are not familiar with how a '10-key' works, while 'Adding Machine: 10 Key Calc' uses inverted number/operator entry, the same as a 10 Key adding machine, commonly used by Accountants and CPA's.

Q2. Can I touch-type?
A2. Checkout the iPad version with its large (1:1) keypad and several aids for touch-typing.

Q3. How can I quickly clear the paper tape?
A3. Just double-tap the round 'i' (info) button to clear the paper tape.

Q4. How can I edit an incorrect number or add & delete lines from the paper tape?
A4. Touch any line of the paper tape to go into edit mode. Touch Add or Delete Line. You can also edit numbers, and split Add/Sub or Mul/Div groups. Press Done to return to Calculator mode

Q5. Tell me about Email, Printing, and Exporting a Paper Tape.
A5. From the Export dialog, select from: Email, Print, Copy or Open-In. Email includes a pdf attachment. Print requires an AirPrint capable printer. Open-In will cause a menu of 3rd party Apps to appear that can receive a hardcopy of your paper tape; for example, iBooks, DropBox, and 3rd party printer Apps for Brother, HP, Epson, Canon and more. With these print directly to a network reachable printer (even if it is NOT AirPrint capable).
